Castle Game Engine is a cross-platform 3D game engine written in Object Pascal. It includes a flexible system of 3D objects, with out-of-the-box levels, items, intelligent creatures, and more. Rendering and processing of 3D models in X3D, VRML, Collada, and other formats is implemented. Many graphic effects are available, including shadows, bump mapping, shaders, mirrors, and screen effects.
RoseThorn is a cross-platform library for 2D and 3D games running on GNU/Linux (and possibly other Unix-like OSes) and Windows. Features include: hardware accelerated 2D and 3D rendering; Ogg and WAV Sound support with OpenAL; Lua scripting; BMP, JPEG, and PNG image loading and saving (from screenshots); easily created and modified user interfaces with XML and CSS, combined with Lua event handling; separate 2D and 3D libraries; support for multiple fonts in both TTF and bitmap formats; support for OBJ, 3DS, MD5, and RTM model formats; skeletal animation (a work in progress); support for UDP and TCP networking; thread and mutex support; a Simple Shader API; 2D animated sprites; and some basic cryptography support. There is simple event management, with key/mouse bindings easily customized from the in-game console, config file, command line, or GUI.
Revised is a visual editor (or wizard/assistant/GUI) for Ren’Py, the visual-novel game editor. Ren'Py has a lot of capabilities, and Revised's purpose is not to allow everything that Ren'Py can do, just some of the basics. You can think of it as a step-by-step wizard to create the skeleton of a Ren'Py game.
planes is a hierarchical surface framework for PyGame. It introduces a "Plane" class which extends PyGame's "Surface" functionality, offering a hierarchy of mouse-sensitive, draggable Surfaces that can be used as sprites, windows, icons, or other interactive elements. In addition, the planes.gui module uses planes to provide basic GUI elements like container, label, text box, option list, and button.
OSGET is a mobile game engine template based on the EMO framework, which uses the Squirrel scripting language to support Android and iOS. The template includes common gaming features such as an introductory splash page, changing between level scenes, integrated player control, physical behaviors such as velocity against gravitational force, object collision detection and handling, background scrolling, playing of different audio channels, event triggering at timeout intervals, level missions, final level missions with bosses, and score submission through HTTP. It is based on the MVC pattern.
GammaMOO is a fork of the LambdaMOO server with numerous cleaned-up patches and modern MOO functionality. This currently includes multicore support, object caching and other acceleration features, enhanced file I/O, UTF support, new built-in data types, and stability improvements with 64-bit support in progress.
